PUIVIP.

SPECIFICATION forming part of Letters Patent No. 243,744, dated July 5,1881.

Application filed July 13, 1880.

To all whom it may concern:

Beit known that I, GEORGE WILSON, ot Parliament Street, in thelcity otWestminster, England, have invented an improved Apparatus for Forcing ortaising Water, and also for other purposes, (for which l have obtained apatent in Great Britain, No. 4,733, bearing date November 20, 1879,) ofwhich the following is a specification.

My invention consists ot' a wheel inclosed in a casing and capable ot'being rotated by steam or other power, this wheel and casing being soarranged that there is a cavity or channel (or cavities or channels)between the periphery ofthe wheel and casing, this waterpassage betweenthe Wheel and casing extending partly but not completely around thewheel, and communicating at one end with a supply pipe or conduit and atthe other end with an exit pipe or conduit, as more particularlyhereinafter described.

The apparatus consists of what I term a Wheel having a cavity orcavities sunk in and extending around its periphery. The transversesection or sections of' the said cavity or cavities sunk in theperiphery of the wheel may be formed of parabolic, circular, elliptical,or of any'other curves, either concave or convex or partly concave andpartly convex; or the form may be angular or partly angular and partlycurved. The Wheel is inclosed and caused to revolve around its axisWithin an airtight casing. The Hat ends or sides of the Wheel revolveclose to the sides of the casing; but the portion of the casinginclosing and extending around the periphery of the wheel may be a plainsurface or concave or convex, of a circular, elliptical, parabolical, orof any other shape. The suction and discharge of the water respectivelyto and from the Wheel is through a passage or passages inthe casing atthe periphery. The Waterilows through the samepassages Whichevermay bethe direction the wheel is caused to revolve; but the suction anddischarge passages for the water to iiow through when the' wheel iscaused to revolve in one direction respectively become reversed, ordischarge and suction passages when the wheel is caused to revolve inthe contrary direction.

Theac'tion of the apparatus is as follows: The air-tight casin ginclosing the wheel and also (No model.) Patented in England November Q0, 1879.

the suction-pipe being full ofwater, (in a siniilar manner to anordinary centrifugal pump,) the wheel is then caused to revolve by steamor any other power with the requisite velocity in the desired direction,and the action ofthe cavity or cavities sunk in the periphery of therevolving wheel upon the water causes the latter to be forced byfriction, or by friction and suction, round in the direction the wheelrevolves, through the apparatus and discharge pipes or passages.

My said invention, besides being applicable as a pump for the purpose oflifting or forcing water or other iiuids, is also applicable for forcingwater out of the stern or other part of a vessel in any desireddirection for propelling the saine, or out oi' the side or sides ofthevessel for steering the same.

In order that my said invention may be clearly understood, I will nowgive general illustra tions of the saine.

Referring to the hereinbefore description and to the drawings hereuntoannexed, Figures l and 2 are sections through the apparatus, in whichone cavityis sunk in and extends around the periphery oi' the wheel. Thesolid thick black lines show the wheel, which revolves on the axis g r/on bearings It h. m m is the casing inclosing the wheel, and o is thecavity sunk in the periphery ofthe wheel.

Fig. 3 is a section of a wheel in which four cavities, o o, are sunk iuits periphery.

Fig. 4 shows a section of a Wheel the cavity or cavities of which arepartly angular. Supposing that the wheel is caused to revolve in thedirection shown by the arrow s, the water Will iiow through the suctionpipe or pipes at F and enter tangentially the cavity or cavities of theWheel at Y, and ,after bein g forced through the apparatus by thefrictional action ot' the revolving wheel, the same will entertangentially atYand be discharged through the pipe or pipes at G. If theWheel is caused to revolve in a contrary direction to that hereinbeforelastly described, then Gbecolnes the suc tion and F the discharge pipeor pipes for the water. The casing is formed in such a manner, as shownat Y Y', that in either direction in which the wheel is caused torevolve the Water forced partly around the casing by the action oftherevolving wheel ows tangentially from IOO the suction pipe or pipes intothe cavity or cavities of the wheel, and also tangentially from thelatterinto the discharge-pipe or pipes. The distance betweenY and Y-thetangeutpoints `for the entrance and discharge of the water into and fromthe cavity or cavities of the wheel-is dependent on the desiredarrangement of the suction and discharge pipes with regard to thecasing.

Fig. 5 shows the suction and discharge pipes H J (one of which is shownstraight and the other curved) arranged in such a manner that the waterwill be acted upon bythe revolving Wheel and forced round the casingthrough the distance of a semicircle.

The suction and discharge pipes and also the apparatus should beconstructed in such a manner as to cause the water to 110W in continuousvolumes of uniform or nearly uniform sectional areas.

In the application of my improved apparatus as a pump for the purpose oflifting or forcing Water or other fluids, one of the pipes, G or F,

would be the suction and the other the dis charge pipe for the Water,the arrangements being as for ordinary centrifugal pumps. This pump canalso be used for propelling or steering vessels by forcing the Waterfrom the stern or other part in various ways.

Having thus fully described my said invention and the manner ofperforming the same, I wish it to be understood that I claim- My improved apparatus,consistin g ofa wheel iuclosed in a casing and capableof being rotated by steam or other power, the wheel and casing being soarranged that there is a cavity or channel (or cavities or channels)between the periphery ofthe Wheel and the casing, extending partly butnot completely around the Wheel,V

and communicating at one end ,with a supply pipe or conduit and at theother end with an exit pipe or conduit, substantially as described.

V GEORGE WILSON.
